This chapter provides an example to illustrate the benefits of using the itinerary‐based fleet assignment model (IFAM) over the basic fleet assignment model (FAM). The main difference between the two models is that the FAM model is formulated at the flight level, while the IFAM model is itinerary based. Similar to the IFAM example presented in this context, the basic FAM problem is formulated using the Excel Solver. The chapter presents the problem solution steps in formula and value formats. According to the example provided, the solution of the basic FAM tends to minimize the spilled revenue at the flight level, and hence large aircraft are used for all flights. On the other hand, the IFAM model considers that the spilled demand can be recaptured on other itineraries. Thus, large aircraft are not necessarily needed for all flights.
